Applications
 Interrupt switch
 Limit switch
 Door position
MP1021 Series
Digital Hall-effect position sensor in plastic fl ange-mount housing.
Features
 Three sensing orientations available in aconvenient fl ange mount housing
 Excellent output stability over operating temperature range
 Compatible with unregulated power supply
 Reverse battery protection to -24 V DC
 Open Collector (NPN) output can be used with bipolar switch or cmos
logic circuits with suitable pull up resistor
 MP102103 – north pole activated unipolar switch
- Output switches low (off) when the magnetic fi eld at the sensor
exceeds the operate point threshold.
- Output switches high (on) when the magnetic fi eld is reduced to
below the release point threshold
 RoHS Compliant

Dimensions
inches (mm)
All tolerances ±0.005 (0.13) unless otherwise noted.
Notes: These sensors require the use of an external pull-up resistor, the value of which is dependent on the supply voltage. See page 27 for recommendations.
Pull-up resistor should be connected between output (Green) and Vcc (Red).
